Frequently Asked Questions
Common questions about the free online number formatter.
Type the number, choose a grouping style and pick the thousands separator you want. The
formatted result updates as soon as any setting changes.
Indian grouping keeps the last three digits together and then groups the rest in pairs, so
1234567 is written as 12,34,567.
Half up sends 2.5 to 3, half even sends 2.5 to 2, round up moves away from zero, round down
moves toward zero and truncate drops the rest.
Percent mode multiplies the value by 100 and appends a percent sign, so 0.1234 becomes 12.34
when two decimal places are selected.
Significant figures round to a fixed number of meaningful digits, which suits measurements,
so 1234 with three significant figures becomes 1230.
Paste text such as 12,34,567.89 into the parse box. Grouping, symbols and percent signs are
stripped, and the note explains how separators were read.
The tool reports that the value is not numeric and leaves the result blank instead of
guessing, so you always know that the input was rejected.
